The objectives of this project are:

1. to investigate potential vulnerabilities of a CubeSat constellation (i.e., a network of CubeSats orbiting together);
2. to investigate potential cyberattacks exploiting these vulnerabilities of a CubeSat constellation, especially those that have a high effectiveness-to-cost or high reward-to-cost ratio; and
3. to devise countermeasures against these cyberattacks in a learning-based framework.
